received adidas warranty replacement shoes but...

I sent the my shoes on Dec.1 and received the replacement shoes today.
Much quicker than I expected.
As soon as I open the box, it was White and red color. Actually, I liked the color. when I tried to wear the shoes, I realized that the shoes is way to small then I checked the box. OMG:shock: they sent the wrong size shoes:evil:
I wear 7 1/2 but they sent 6 1/2 shoes.

I sent the email to customer service but I should call tomorrow.
Does anyone know Adidas shoe warranty department phone number?
where am I supposed to call?

In the United States: 1-800-448-1796. Adidas customer service is usually extremely helpful with the shoe replacement warranty service. Best time to call is usually in the morning before 11 a.m., East Coast time.
